Description

The hollow brick mould

Technical field

The utility model relates to a kind of mould of working pressure machine moulding adobe, particularly a kind ofly is used to make the mould that brick moulding with holes is used.

Background technology

The existing mould of producing half-dried material mould brick goods with forcing press; the degree of depth in its pattern chamber is fixed; if this pattern or mould adopt relatively difficulty of brick that the brick of different compression ratio raw material production same intensity or identical compression ratio raw material produce varying strength (packing), reason is to adjust feeding quantity.

In addition, if produce hollow brick, the core print that is used for hole forming in the then existing pattern mainly is two kinds of designs, the one, core print is welded in the die cavity, its shortcoming is to cause reinforced not freely easily, particularly has the big slightly particle of granularity will cause paulin material phenomenon in the raw material, influences the intensity of moulded products.The 2nd, be welded on the pressure head core print is naked, the major defect of this structure is that core print is easily hung the limit with moulded products when the demoulding, makes whole adobe breakage.

The 3rd, after the moulded products demoulding, die cavity cavity in aggregates, if several pattern chambeies are arranged on the same pattern, because feeding device various die cavity in advancing reinforced process is that order is reinforced, the die cavity that first pan feeding often occurs is full, and the anterior material of truck uses up, then Jia Liao die cavity is not filled it up with as yet or is not added reality, and still there is the unspent phenomenon of part material at the truck rear portion.In addition, also can be owing to the reinforced duration difference of various die cavity, inlet amount is also inconsistent, the incongruous serious quality problems of brick intensity (packing) that same pattern extrudes occur.

Summary of the invention

The utility model has designed a kind of hollow brick mould at the deficiency that above-mentioned prior art exists.

Hollow brick mould of the present utility model, comprise pattern, counterdie pressure head and the patrix pressure head that is fixed with the perforation core print, wherein said patrix pressure head is made up of pressure head plate and core print base plate, described perforation core print is fixed on the lower surface of core print base plate, on the pressure head plate, be provided with and the corresponding hole of passing through of described perforation core print, the pressure head plate is fixed on the push rod lower end, the upper end of described push rod is passed spring bottom plate and a stop is arranged in the end of push rod, depression bar passes spring bottom plate and links to each other with the core print base plate, spring bearer plate is fixed on depression bar top, between spring bearer plate and spring bottom plate spring is arranged.

Hollow brick mould of the present utility model, because the patrix pressure head is divided into pressure head plate and core print base plate, and the perforation core print places between pressure head plate and the core print base plate, and deviate from from adobe prior to the pressure head plate by spring control punch core print, can not dial bad adobe when making the demoulding of perforation core print, improve the adobe yield rate, reduced cost.Core print is fixed on the core print base plate owing to will bore a hole, and makes the working surface of pressure head plate keep bright and clean, can not cause adhesion with adobe, so that influence the fineness of adobe.The 3rd, owing to, make the pattern degree of depth to adjust at any time with product needed with counterdie pressure head double as pattern base plate.The 4th, because counterdie pressure head double as pattern base plate with activity, can be when reinforced with after adding truck integral body and placing the pattern upper surface, make raw material descend gradually and make the charging simultaneously of each die cavity along with the counterdie pressure head, avoided adding truck reinforced priority difference that is produced in progradation owing to charging, and cause each die cavity charging inequality, same pattern with batch the spotty consequence of finished product adobe.

The specific embodiment

Comprise pattern 2 with reference to accompanying drawing 1-3 hollow brick mould of the present utility model, 3, one pressure head plates 6 of counterdie pressure head and core print base plate 5, the two forms the patrix pressure head.Perforation core print 4 is welded on the lower surface of core print base plate 5, perhaps is fixed on the core print base plate 5 by helicitic texture.Cross sectional shape of this perforation core print 4 be circle or squarely all can.Fixed form also can adopt alternate manner, such as bolting etc.Be provided with the pass through hole corresponding with described perforation core print 4 on pressure head plate 6, perforation core print 4 passes from the described hole 14 of passing through.Pressure head plate 6 is fixed on the lower end of two push rods 7, and the via hole of spring bottom plate 8 is passed in the upper end of this push rod 7, in push rod 7 upper ends a stop is arranged.Push rod 7 can slide up and down along the via hole on the spring bottom plate 8.Spring bottom plate 8 is enclosed within on the depression bar 11 and can slides up and down.Pressure head plate 6 can slide up and down along perforation core print 4.It is fixing with core print base plate 5 that depression bar 11 passes spring bottom plate 8.Spring bearer plate 10 is fixed on the top of two depression bars 11.Between spring bearer plate 10 and spring bottom plate 8, be provided with spring 9.Above-mentioned spring 9 is provided with around depression bar 11.

In actual the use, pattern 2 is placed on the forcing press, and counterdie pressure head 3 links to each other with the bottom oil cylinder, and these 3 whiles of counterdie pressure head are as the base plate in pattern chamber.It is the most the next that patrix pressure head 1 is in spring bottom plate 8 by spring force.Spring 9 is in open configuration when static, and push rod 7 is pushed into the most the next of perforation core print 4 with pressure head plate 6, as shown in Figure 3.Perforation core print 4 lower surfaces flush with pressure head plate 6 lower surfaces.
